Answer:
60
Step-by-step explanation:
The sum of the angles of a triangle is 180
x+x+x = 180
3x= 180
Divide by 3
3x/3=180/3
x = 60
Pattern #1: (I think it should have started with 7, not 17)
7 -> 14 either added 7 or multiplied by 2
14 -> 8 subracted 6
8 -> 16 either added 8 or multplied by 2
16 -> 10 subtracted 6
10 -> 20 added 10 or multiplied by 2.
The pattern seems to be multiply by 2, then subtract 6, repeat.
14 -> 28
28 -> 22
Pattern #2:
11 -> 13 added 2
13 -> 16 added 3
16 -> 20 added 4
20 -> 25 added 5
25 -> 31 added 6
31 -> 38 added 7
to finish...
38 + 8 = 46
46 + 9 = 55
Answer :
Given that the base of the triangle is x m, the height is 3m less than twice it's base then the height will be represented by the equation:
(2x-3) m
Thus the area will be:
Area=1/2bh
Area=1/2x(2x-3)=17.5
x^2-1.5x=17.5
Writing the above equation is quadratic form of ax^2+bx+c=0 we get:
x^2-1.5x-17.5=0
